All,

I'm configuring Sharepoint to use forms authentication with LDAP/Active Directory. I'm new to Sharepoint, so if this is obvious, please point me in the right direction.

Whenever I attempt to log in with a bad account or password, I get the very friendly (and correct) error message,

The server could not sign you in. Make sure your user name and password are correct, and then try again.

... which implies that Sharepoint is able to communicate with AD. If I log in with a valid account, I get a page that says:

(I added the grey bar to cover up the login name)

Any suggestions? The account I'm logging in with is an administrator and has been granted full control in central administration.

Also, interesting note: If I click the "sign in as a different user" link, and attempt to sign in using with the same credentials I just used, the site just redirects back to the login page, with no error or status message. If I then manually enter the site url, it again shows the "Error: Access Denied" page. Argh.
